Title:
UNDERWATER COMMUNICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/016862
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of computer applications, and provides an underwater communication method and a device. The method comprises: generating electrical signal information to be sent; determining, according to a pre-determined manner of vortex sound field generation, transmission information of a vortex sound field signal corresponding to the electrical signal information; passing the electrical signal information through a pre-determined excitation transducer according to the transmission information of the vortex sound field signal, and generating the vortex sound field signal; and sending the vortex sound field signal to a pre-determined receiving device. The transmission information of the vortex sound field signal corresponding to the electrical signal information is determined according to the pre-determined manner of vortex sound field generation, and any vortex sound field can be generated or received by a pre-determined underwater area array transducer, thereby achieving core sound field propagation of vortex sound communication, and reducing underwater transmission signal distortion during an encoding and decoding process.
